>>28801287So far it seems that Nazuna is for the public happy-go-lucky vtuber persona, Mikeneko is for the person behind but still public (so things like casual but a bit more personal stuff like twitcasts or face cam streams, and publicly dennouncing things like antis activities)
and the other one is for deeper feelings and day to day issues for the most gachikois that she feels would be a bother for the people following her other accounts.
Of course, they overlap in some places and the distinction makes less sense now that she's in a company that cares less about dividing between a public and a private persona but the longer you're following her the more you get used to it.
It may seem schizo but as someone following other jp chuubas i'm kinda thankful that they don't just use their main accounts to vent and express their opinions on public issues.
